The monomers of DNA are called nucleotides. Nucleotides have three components: a base, a sugar (deoxyribose) and a phosphate residue. The four bases are adenine (A), cytosine (C), guanine (G) and thymine (T).
What are the three components of a DNA monomer quizlet?
Monomer that makes up the polymer DNA. Made up of three different components: phosphate group, pentose (5 carbon) sugar deoxyribose, and one of four organic nitrogen bases including adenine, guanine, cytosine, and thymine.
What are the 3 components parts of DNA?
In turn, each nucleotide is itself made up of three primary components: a nitrogen-containing region known as a nitrogenous base, a carbon-based sugar molecule called deoxyribose, and a phosphorus-containing region known as a phosphate group attached to the sugar molecule (Figure 1).
What does the D in DNA stand for?
= DNA is the chemical name for the molecule that carries genetic instructions in all living things.
What are the building blocks of DNA?
DNA is a molecule made up of four chemical bases: adenine (A), cytosine (C), guanine (G), and thymine (T). For the two strands of DNA to zip together, A pairs with T, and C pairs with G. Each pair comprises a rung in the spiral DNA ladder.
What are the four nitrogenous base of DNA?
Adenine, thymine, cytosine and guanine are the four nucleotides found in DNA.
What charge does DNA have?
DNA is negatively charged, therefore, when an electric current is applied to the gel, DNA will migrate towards the positively charged electrode.
What are the monomer building blocks that make up the structure of DNA?
Nucleotides. DNA and RNA are made up of monomers known as nucleotides. The nucleotides combine with each other to form a polynucleotide: DNA or RNA.
What are the six components of DNA?
DNA is made up of six smaller molecules ” a five carbon sugar called deoxyribose, a phosphate molecule and four different nitrogenous bases (adenine, thymine, cytosine and guanine).
What name is given to A single unit of DNA?
The basic unit used to make a strand of DNA is called a nucleotide. A single basic unit or “building block” of DNA consists of a sugar , a phosphate group and a base. Sugars are rings of carbon and oxygen atoms.
What does the R in RNA stand for?
RNA, abbreviation of ribonucleic acid, complex compound of high molecular weight that functions in cellular protein synthesis and replaces DNA (deoxyribonucleic acid) as a carrier of genetic codes in some viruses.
What are the 3 basic building blocks of DNA?
DNA is made of chemical building blocks called nucleotides. These building blocks are made of three parts: a phosphate group, a sugar group and one of four types of nitrogen bases.
What is the difference between the 4 building blocks of DNA?
Each strand of DNA is made of four types of molecules, also called bases, attached to a sugar-phosphate backbone. The four bases are adenine (A), guanine (G), cytosine (C), and thymine (T). The bases pair in a specific way across the two strands of the helix: adenine pairs with thymine, and cytosine pairs with guanine.
What are the 3 main parts that make the building blocks of DNA?
The building blocks of DNA are nucleotides, which are made up of three parts: a deoxyribose (5-carbon sugar), a phosphate group, and a nitrogenous base (Figure 9.3). There are four types of nitrogenous bases in DNA.
Where is the nitrogenous base in DNA?
The nitrogenous bases point inward on the ladder and form pairs with bases on the other side, like rungs. Each base pair is formed from two complementary nucleotides (purine with pyrimidine) bound together by hydrogen bonds. The base pairs in DNA are adenine with thymine and cytosine with guanine.
How many base pairs does A gene have?
Human genes are commonly around 27,000 base pairs long, and some are up to 2 million base pairs.
